The utility model includes a furnace body. A fire hole is connected with the coal gasification firebox. A reduction tank and an exhaust road are arranged in the hearth of the furnace. The structural points are: the reduction tank consists of a level tank and an oblique tank; the angles of the level tank and the oblique tank are 60 to 70 DEGs; the condensation mould and dumping java plug are respectively arranged at the outlet of the level tank and oblique tank; Heat storage bricks are arranged at the hearth of the reduction tank. The utility model has high efficiency in magnesium smelting and can increase the durability of the reduction tank.
Description
Technical field:
The utility model relates to the improvement of smelting silicothermic process magnesium reducing furnace structure.
Background technology:
Employed reduction furnace in China's magnesium-smelting silicothermic process process, its reduction jar is and is horizontally disposed with.This stove must vacuum breaker, open and jar get magnesium, skim after adding material, reacting by heating, and a working cycle needs 10-12 hour.Its shortcoming be manually skim, working conditions is abominable, the time is long, efficient is low; In addition, reduction jar accumbency and directly contacts with flame in burner hearth, and reduction in the course of time jar produces a creep, causes reduction jar useless labor fracture, work-ing life is short.
Summary of the invention:
The utility model just provides a kind of refining magnesium efficient that improves, and prolongs the reduction magnesium smelting reducing stove in jar work-ing life.
The technical solution adopted in the utility model is: the utility model comprises body of heater, the fire hole that advances of body of heater links to each other with the gasification of coal combustion chamber, be provided with reduction jar, exit duct in the burner hearth of body of heater, its structural feature is that the reduction jar is made up of horizontal retort, oblique Storage Tank, angle is 60-70 ° between horizontal retort and the oblique Storage Tank, and the exit of horizontal retort, oblique Storage Tank is respectively arranged with condensing crystallizer, slag dumping plug; Be provided with gitter brick in the reduction jar outer burner hearth.
The beneficial effects of the utility model:
1, refining magnesium efficient height:
Because the utility model is provided with oblique Storage Tank, pellet is added by the reduction jar very smoothly fill, and not damaged, thus make pellet fully absorb heat, improved production efficiency; As long as what is more important is opened the slag dumping plug, under the effect of gravity, the slag in the reduction jar can be automatically in the reduction jar a removal, thereby saved work and time, improved working conditions, shortened the production cycle;
2, improved the work-ing life of reduction jar:
Owing in reduction jar outer burner hearth, be provided with gitter brick, can prevent that flame from directly jar contacting with reduction, therefore, reduced the creep of reduction jar, the work-ing life of having improved the reduction jar.

Embodiment:
The utility model comprises body of heater 1, the fire hole 10 that advances of body of heater 1 links to each other with gasification of coal combustion chamber 11, be provided with reduction jar 7, exit duct 5 in the burner hearth 3 of body of heater 1, reduction jar 7 is made up of horizontal retort 15, oblique Storage Tank 16, angle a is 60-70 ° between horizontal retort 15 and the oblique Storage Tank 16, and the exit of horizontal retort 15, oblique Storage Tank 16 is respectively arranged with condensing crystallizer 8, slag dumping plug 12; Be provided with gitter brick 9 in the burner hearth 3 outside the reduction jar 7.
The patent No. of gasification of coal of the present utility model combustion chamber 11 is: ZL94231473.5.Condensing crystallizer 8 is a prior art.
Detachable furnace roof 17 of the present utility model,, form by the fire-resistance rammed mass ramming, can use by a plurality of dismountable furnace roof 17 stacks.The utility model is provided with detachable furnace roof 17, provides convenience for changing or overhaul reduction jar 7.
Furnace bottom 18 from top to bottom is that alumina firebrick 13, refractory fiber blanket 14, alumina firebrick 13, refractory fiber blanket 14, steel plate 19 are formed successively.
Furnace wall 6 is made up of steel plate 20, refractory fiber blanket 2, alumina firebrick 4, refractory fiber blanket 2, alumina firebrick 4 successively.
Narrate a course of action of the present utility model below:
At first, in reduction jar 7, install the magnesium pellet.The flames that produce in the gasification of coal combustion chamber 11 are through advancing fire hole 10 to burner hearth 3 internal heating reduction jars 7, and after heat, the magnesium pellet produces magnesium vapor to horizontal retort 15, make crude magnesium at the condensing crystallizer 8 magnesium vapor crystallizers that are provided with through the exit again.Then, open slag dumping plug 12, residue is discharged reduction jar 7.
